To reduce the risk of eye injury always wear proper eye protection. Always use the appropriate deflector for the type of cutting attachment, as explained in your instruction manual.

Rated 5 out of 5 by BrandonBOCOMO Great Trimmer but a pricey FS 100 RX The 100 RX is lighter than the 90 I tried and more powerful and only $25 bucks more !! It gets a little hot on the arm if your resting it against the trimmer's motor as you work, but that's a bad habit I have. Very powerful, easy to start. A little pricey but dependability is what counts. Nothing worse than having to fiddle with equipment when your trying to get something done. Use only non-ethanol fuel with your oil mix !!! I run premium with no ethanol fuel with great success. July 14, 2015

Rated 5 out of 5 by abrahamv16 our new standard We were always intrigued about these trimmers but we didn't need any until they stole our other trimmers. And the sweet out of this bittersweet story is this specific tool. Our commercial business demands powerful, lightweight, and dependable tools like this. We decided to try this trimmer since we love all of our other Stihl products and we needed to replace the stolen ones. I'm glad we opted for this tool. It is lighter and more powerful then what we were used to. So now this will be our new go-to string trimmer. Nothing less. May 1, 2015

Rated 5 out of 5 by Gene3 This product light and piwerful Have been using 100RX 4 4 years now I have 4 of them on my trailer now. Run all day start right up. Light and powerful Great weed eater April 25, 2015

Rated 5 out of 5 by Philbos81 Love it! This is the best trimmer I've ever used. Been in the lawncare business for 15 years now and have used a lot of products. This trimmer beats them all by a long run. Some say the price is a little high but you get what you pay for. I definitely recommend it to anyone looking for a powerful, light weight trimmer that you can sling around real quick from a flat edge to a straight edge I don't even run it full throttle. I'd probably take off flying if I attempted that. Buy this trimmer and never look back. April 13, 2015

Rated 5 out of 5 by nicktpm Fs 100 rx Trimmer Going on year two with this bad boy. I have 4 other pro trimmers including (2) 110's, a 130 and a Honda. The Stihl 100 has the best power to weight ratio out of any trimmer I've ran. This has the same power as a fs 110 with less weight. One con is this model trimmer is for line use only not for blades, but that is made up with weight savings, power and antivibes. If you want a dependable string trimmer you can run wide open all day that can save your back and arms from unnecessary fatigue this is your trimmer. We still use the 110s daily and they are great, reliable, multipurpuse trimmers. The 130 is our "brushcutter" and has blades installed. Can't beat stihl trimmers. April 9, 2015

Rated 5 out of 5 by Topgrass Great overall product and unmatched reliability. Same power as the 110 only lighter.I can draw more line then in the Fs90r and doesn't affect the power even in thick grass.Doesn't hesitate when switching throttle from low to high near trees etc.The weight allows me to trim more and faster with less fatigue.Reliable and has handled all the abuse my guys throw at it.It's everything I wished for in one package.
